Ecological distribution conflicts as forces for sustainability

Can ecological distribution conflicts turn into forces for sustainability? This overview paper addresses in a systematic conceptual manner the question of why, through whom, how, and when conflicts over the use of the environment may take an active role in shaping transitions toward sustainability. It presents a conceptual framework that schematically maps out the linkages between (a) patterns of (unsustainable) social metabolism, (b) the emergence of ecological distribution conflicts, (c) the rise of environmental justice movements, and (d) their potential contributions for sustainability transitions. The ways how these four processes can influence each other are multi-faceted and often not a foretold story. Yet, ecological distribution conflicts can have an important role for sustainability, because they relentlessly bring to light conflicting values over the environment as well as unsustainable resource uses affecting people and the planet. Environmental justice movements, born out of such conflicts, become key actors in politicizing such unsustainable resource uses, but moreover, they take sometimes also radical actions to stop them. By drawing on creative forms of mobilizations and diverse repertoires of action to effectively reduce unsustainabilities, they can turn from ‘victims’ of environmental injustices into ‘warriors’ for sustainability. But when will improvements in sustainability be lasting? By looking at the overall dynamics between the four processes, we aim to foster a more systematic understanding of the dynamics and roles of ecological distribution conflicts within sustainability processes

Una herencia en Manaos (anotaciones sobre historia ambiental, ecología política y agroecología en una perspectiva latinoamericana)

Este artículo pretende explorar algunas vinculaciones de la agroecología con la historia ambiental, en sus escalas macro y micro, y con la ecología política. Una clave de interpretación es un interrogante sobre la identidad latinoamericana, que es percibida como articulación y sedimentación de varias herencias diferentes,en la cultura, la tecnología, los paisajes y la naturaleza

Invasiones biológicas

216 p.Premeditado o involuntario, el transporte e introducción de especies biológicas fuera de su área nativa es tan antiguo como la propia humanidad. El rápido aumento en el tránsito de personas y mercancías ligado a la creciente globalización ha multiplicado, sin embargo, la escala espacial de las introducciones, y el número de organismos que se transportan de una región a otra. Muchas de estas especies exóticas tienen la capacidad de alterar seriamente el funcionamiento de los nuevos ecosistemas en los que son introducidas, causando grandes daños no sólo ecológicos sino también económicos: plagas que reducen la producción agrícola, plantas cuyo polen es alergógeno, plantas y animales que dañan infraestructuras o afectan a nuestros alimentos. Además, el cambio climático facilita la expansión de especies exóticas de zonas cálidas, mientras que el aumento de las perturbaciones de origen humano favorece a las especies oportunistas y de rápido crecimiento. En este libro se repasan ideas de biología y ecología que permiten comprender las invasiones biológicas, qué las hace posible y cuáles son sus efectos sobre los ecosistemas receptores. Se incluyen también nociones sobre el control y la gestión de las invasiones, y numerosos casos concretos. El equipo que ha colaborado en esta obra, un total de 52 autores, desea aportar una visión integradora sobre las invasiones biológicas que sirva para informar y concienciar a toda la sociedad de que estamos frente a un grave problema

C-reactive protein may misdiagnose prosthetic joint infections, particularly chronic and low-grade infections

BACKGROUND: Periprosthetic tissue cultures, sonication and synovial fluid cultures remain the gold standard for prosthetic joint infection (PJI) diagnosis. However, some 15-20% culture-negative PJI are still reported. Therefore, there is the need for other diagnostic criteria. One point of concern relative to the different definitions of PJI is as to the inclusion of the c-reactive protein (CRP) and the erythrocyte sedimentation rate (ESR) as diagnostic criteria for PJI despite them being non-specific inflammatory blood tests. PURPOSE: The purpose of the present study was to determine the relevance of CRP and the ESR in the diagnosis of PJI. METHODS: All PJI with positive cultures over a two-year period in two hospitals were reviewed. The main variables of the present study were the type of prosthesis and the CRP level. More information was recorded in those patients with normal CRP: radiographs, physical examination records and the ESR. RESULTS: Seventy-three patients were included in study. Pre-operative CRP levels were normal (lower than 0.8 mg/dl) in 23 patients, representing 32% of all PJI with positive cultures. Low virulence micro-organisms, 12 coagulase-negative staphylococci and four P. acnes, grew in most of them. They represented 70% of all PJI with normal CRP levels. In addition, 17 patients (23% of all PJI with positive cultures) had a normal ESR, a normal physical examination (they only presented with pain) and no clear loosening was observed in the radiographs. CONCLUSIONS: Per the American Association of Orthopaedic Surgeons (AAOS) guidelines or the Musculoskeletal Infection Society (MSIS), 23% of the patients in the present study with PJI would never have been identified. Blood inflammatory markers such as the CRP level and ESR may not be accurate as diagnostic tools in PJI, particularly to identify low-grade and chronic PJI
